The innovative design features a separation between the product area and the load area, combined with an updraft cooling system using a top turbine fan, and an epoxy insulation board with ventilation holes. This achieves efficient insulation between layers and comprehensive anti-static protection, preventing potential safety hazards such as short circuits and static electricity during the testing process from the very beginning, and safeguarding both the equipment and the operators' safety. The cabinet is equipped with a folding double-layer transparent glass door. The product area is designed as a closed space and features dedicated lighting fixtures, ensuring the stability of the aging environment while also facilitating real-time observation of the testing status and timely detection of abnormalities by the staff. The shelves support reversible adjustment, significantly expanding the operational space and enhancing operational convenience. A set of high-quality casters is installed at the bottom, allowing for flexible movement of the equipment, adjustment of its placement, and perfect adaptation to the diverse production layout requirements of the factory.

II. Core Configuration: High-performance programmable load, compatible with multi-power scenarios for comprehensive testing
The equipment is equipped with the programmable electronic load module independently developed by Zhongyuanyuan. It supports various interface protocols such as RS232, RS485, CAN, CANFD, and MODBUS, and implements optical isolation to ensure stable data transmission and strong anti-interference ability. It innovatively adopts a structure without electrolytic capacitors and relays, effectively extending the service life of the module. It can stably meet the requirements of long-term continuous aging tests, significantly reducing equipment wear and tear and the cost of later maintenance, thereby saving operating expenses for the enterprise. The module supports five flexible loading modes: CC (constant current), CV (constant voltage), CR (constant resistance), CP (constant power), and LED. The channels can be freely combined in series or parallel, without the need to additionally equip dedicated test modules. It can easily adapt to different specifications and types of power supply test requirements, and has a wider adaptability.

The test coverage is comprehensive and can meet the aging requirements of power supplies of various power levels: It supports independent operation of a single channel, and can also achieve combinations of dual channels, triple channels, quadruple channels, etc. It can more calmly handle the aging tests of high-power power supplies ranging from 50W to 10KW. The test accuracy is up to ±(1% + 0.05% FS), and it can accurately monitor core parameters such as voltage, current, power and ripple in real time, ensuring the authenticity and reliability of the test data. This provides precise and powerful evidence for product quality determination, helping enterprises strictly control product quality.

III. Electrical Control and Temperature Control: Intelligent and precise regulation, safe and stable with the option for remote monitoring.
The electronic control system adopts 380V three-phase five-wire standard power distribution. It innovatively supports dual modes of computer intelligent monitoring and manual electric control, allowing for flexible switching. It can adjust the operating status according to the working environment and the operation habits of personnel. The operation is convenient and efficient, with low learning difficulty, and it combines intelligence and humanization. The wiring method is simple and reliable, significantly reducing wiring time and improving work efficiency. The control panel is equipped with a three-phase voltage meter, start switch, and emergency stop switch, which can clearly display the input voltage and the operating status of the equipment in real time. This facilitates staff to quickly grasp the equipment situation and promptly handle abnormalities, thus strengthening the operation safety defense line.

The temperature control system employs high-precision temperature control technology, enabling precise regulation within the range of normal temperature to 125℃ (customizable according to the actual needs of the customers). Relying on the scientific working principle of "low-temperature heating and over-temperature exhaust air", combined with the closed design of the product area, it ensures uniform and stable temperature in the aging environment, effectively avoiding the impact of temperature fluctuations on the accuracy of test results and guaranteeing the rigor of test data. The equipment is equipped with a comprehensive safety protection mechanism, including grounding protection, leakage switch protection, and automatic power-off protection upon smoke alarm, providing multiple levels of protection to avoid safety risks during the testing process. It supports unmanned operation, significantly reducing labor costs and improving production efficiency, helping enterprises achieve automated and efficient production.

IV. System Functions: Computer intelligent monitoring, complete traceability of data throughout the process
The equipment is equipped with the dedicated power aging monitoring software independently developed by Zhongyu Technology. It offers a lifetime free upgrade service and supports barcode scanning and integration with MES systems. It perfectly meets the needs of enterprise intelligent production management, achieving seamless connection between aging tests and production management, helping enterprises build intelligent testing lines and promoting the improvement and efficiency enhancement of production management. The software can monitor the core parameters such as voltage, current, and power of each power line in real time, automatically determine the quality of the products, and visually distinguish the types of defects through different colors, facilitating staff to quickly screen and handle non-conforming products, significantly improving the testing efficiency.

The system supports multiple programmable functions, allowing for customization of aging parameters based on test requirements, editing of ON/OFF sequences, and enabling automatic voltage switching and flexible load adjustment. It can preset the total aging time, automatically shut off the power after the aging test is completed, achieving full-process automated testing. At the same time, it supports centralized management of multiple devices, further enhancing testing efficiency and reducing manpower input. Additionally, the computer can automatically store aging data reports and generate failure rate charts, enabling full-process traceability of the testing process and data results, providing powerful data support for enterprise quality control and process optimization, and helping enterprises continuously enhance their product competitiveness.
